Brush



March 24, 1959 M. J. BRENNAN BRUSH Filed Sept. 20, 1957 United BRUSHMartin J. Brennan, St. Louis, Mo., assignor to J. S. Costello & SonBrush Company, St. Louis, Mo., a corporation of Missouri ApplicationSeptember 20, 1957, Serial No. 685,174 4 Claims. (Cl. 15-164) Thisinvention relates to brushes, and more particularly to a toilet bowlbrush.

Among the several objects of the invention may be noted the provision ofa brush which is particularly adapted for cleaning toilet bowls andwhich is so formed as to make it easy to clean under the rim of a bowlas well as to clean the outlet part of the bowl; the provision of abrush of this class which is so formed as to have a hook-like portion atthe end of the handle of the brush which is adapted to be hooked underthe rim of a bowl and then moved about to clean under the rim of thebowl; and the provision of a brush such as described which is economicalto manufacture. Other objects and features will be in part apparent andin part pointed out hereinafter.

The invention accordingly comprises the constructions hereinafterdescribed, the scope of the invention being indicated in the followingclaims.

, In the accompanylng drawings, in which one of various possibleembodiments of the invention is illustrated:

Fig. 1 is a front elevation of a brush of this invention, a part of thehandle of the brush being broken away;

Fig. 2 is a side elevation of Fig. 1, illustrating how the brush is usedin cleaning under the rim of a toilet bowl, the latter being shown inphantom;

Fig. 3 is an enlarged portion of Fig. 1 with the brush bristles removedand illustrated in phantom only, in order better to show the formationof the brush; and,

Fig. 4 is a side elevation of Fig. 3.

Corresponding reference characters indicate corresponding partsthroughout the several views of the drawings.

Referring to the drawings, a brush of this invention is shown tocomprise a wood handle 1 and a head 3. The handle, a portion of which isshown broken away in Figs. 1 and 2, may be about one foot long, forexample. It is not necessary that it be made of wood. The head comprisesan elongate twisted wire brush element which consists of a pair of wires5 and 7 twisted around bristles 9. Bristles are provided throughout anintermediate portion of the length of the wires, and the end portionsthereof, which are designated 11, are bristlefree.

The twisted wires 5 and 7 of the brush element 3 are bent at the centerof the length of the element in such manner as to provide a bristledloop L having sides 13 which diverge from the brush tip 15 constitutedby the central portion of the length of the element. The twisted wires 5and 7 of the brush element are further bent at the ends of the sides 13of the loop in such manner as to provide re-entrant bristled portions 17which extend back into the loop L from the ends of the sides 13 of theloop and which lie within the confines of the loop and come together at19 within the loop adjacent its open end. The loop L itself is bent asappears in Figs. 2 and 4 to be curved and thereby to present an arcuateconvex outer surface 21 and an arcuate inner concave surface 23. Thetwisted wires of the element are fur- 2,878,501 Patented Mar. 24, 1 959ice ther bent in such manner that the bristle-free end portions 11 lieside-by-side substantially throughout their length and constitute aterminal part having a portion extending outwardly from the concave side23 of the curved loop, the bristle-free end portions 11 themselves beingfurther bent to provide an end portion 25 extending in the directionaway from the brush tip back toward the open end of the loop L. This endportion 25 extends at an angle to the outwardly extending portion ofparts 11 and is spaced from the concave side of the loop L. The endportion 25 is attached to one end of the handle with a ferrule asindicated at 27. The handle extends in line with terminal end portion 25in the di rection away from the brush tip 15. A length of plastic tubing29 may be applied to the end portions 11. v

As appears in Figs. 2 and 4, the tions 11 and the ends of the sides 13of the loop and the re-entrant portions 17 form a hook-like portion atthe end of the handle which is adapted to be hooked under the rim R of atoilet bowl B as shown in Fig. 2, and moved about to clean under therim. At the same time, the arcuate convex outer surface 21 of the brushmoves about on the interior bowl surface for cleaning it. The brush tip15 is adapted to be entered into the outlet part of the bowl forcleaning it.

In view of the above, it will be seen that the several objects of theinvention are achieved and other advantageous results attained.

As various changes could be made in the above constructions withoutdeparting from the scope of the invention, it is intended that allmatter contained in the above description or shown in the accompanyingdrawings shall be interpreted as illustrative and not in a limitingsense.
